“…However, the taxonomic remarks are reported as collective data considering the occurrence of fungi in soil and in association The various findings of Cladosporium in shelters, tunnels or other structures inhabited by insects have not been exhaustively considered, since in many instances they may derive from environmental contamination rather than direct interaction with the insects. This is the case of reports of C. cladosporioides as the most frequent fungus found in tunnels dug by larvae of the longicorn Rosalia alpina (Coleoptera, Cerambycidae) in wych elm (Ulmus glabra) trees at a Polish conservation site [176] and in mines of lepidopteran leafminers on black locusts (Robinia pseudacacia) [139]. Reports on the occurrence of Cladosporium in food supplies of social insects (e.g., bee bread [177]) and as undesired contaminants in laboratory assays or rearing diets of insects (e.g., reference [178]) have also been disregarded.…”

The range of interactions between Cladosporium, a ubiquitous fungal genus, and insects, a class including about 60% of the animal species, is extremely diverse. The broad case history of antagonism and mutualism connecting Cladosporium and insects is reviewed in this paper based on the examination of the available literature. Certain strains establish direct interactions with pests or beneficial insects or indirectly influence them through their endophytic development in plants. Entomopathogenicity is often connected to the production of toxic secondary metabolites, although there is a case where these compounds have been reported to favor pollinator attraction, suggesting an important role in angiosperm reproduction. Other relationships include mycophagy, which, on the other hand, may reflect an ecological advantage for these extremely adaptable fungi using insects as carriers for spreading in the environment. Several Cladosporium species colonize insect structures, such as galleries of ambrosia beetles, leaf rolls of attelabid weevils and galls formed by cecidomyid midges, playing a still uncertain symbiotic role. Finally, the occurrence of Cladosporium in the gut of several insect species has intriguing implications for pest management, also considering that some strains have proven to be able to degrade insecticides. These interactions especially deserve further investigation to understand the impact of these fungi on pest control measures and strategies to preserve beneficial insects.

“…Basidiomycetous Sistotrema sp., which is reportedly endophytic [ 76 ], may rather be considered a facultative fungicolous saprophyte, since it predominates in stage III trees, leading to increased wood decay. According to Bartnik [ 77 ], the presence of S. brinkmannii in wood during its saprotrophic phase is crucial for xylophagous insects, as this modifies the chemical composition, moisture content, and structure of wood, which, in turn, govern the survival and growth rate of larvae. This screening study for enhancing biocontrol potential against BTC is an immediate contribution to the pioneering studies of Bubák F. [ 78 , 79 , 80 , 81 ] and Japp O.…”

Natural Fungicolous Regulators of Biscogniauxia destructiva sp. nov. That Causes Beech Bark Tarcrust in Southern European (Fagus sylvatica) Forests

et al. 2020

Mycoparasites are a collection of fungicolous eukaryotic organisms that occur on and are antagonistic to a wide range of plant pathogenic fungi. To date, this fungal group has largely been neglected by biodiversity studies. However, this fungal group is of interest, as it may contain potential biocontrol agents of pathogenic fungi that cause beech Tarcrust disease (BTC), which has contributed to the devastation of European beech (Fagus sylvatica) forests. Biscogniauxia nummularia has been demonstrated to cause BTC. However, a trophic association between mycoparasites and pathogenic Biscogniauxia spp., has not been established. This study aimed to taxonomically identify and characterize Biscogniauxia, a fungus causing destructive BTC disease in European beech at Lovćen national park, Montenegro and to uncover the diversity of mycopathogens that are natural regulators of xylariaceous Biscogniauxia stroma formation, associated with beech decline. This finding is supported by distinctive phylogenetic and evolutionary characteristics, as well as unique morphological-microscopic fungal features indicating that Biscogniauxia from Montenegro, which is a major cause of BTC occurring in ancient beech forests at the edge of southern Fagus sylvatica distribution, may be described as a novel fungus specific to Fagus. Its evolutionary nuSSU–complete ITS–partial nuLSU rDNA phylogeny indicates its likely emergence by asexual fusion or introgressive hybridization between diverged B. nummularia and B. anceps species. The name Biscogniauxia destructiva is proposed for the novel fungus, as it is aggressive and highly destructive BTC disease.
